Test Suite

Test Status Code Input and Output
1   Fail
R=1:4;k=2;y_correct = 27.5; a=dont_be_mean(R,k) assert(abs(a-y_correct)<1e-10)

y = [] a = []

Error using assert The condition input argument must be convertible to a scalar logical. Error in Test1 (line 3) assert(abs(a-y_correct)<1e-10)

2   Fail
R=0:8;k=3;y_correct = 493.3125; a=dont_be_mean(R,k) assert(abs(a-y_correct)<1e-10)

y = 453.9375 a = 453.9375

Assertion failed.

3   Fail
R=[1 2 4 6 8];k=4;y_correct = 4666.2; a=dont_be_mean(R,k) assert(abs(a-y_correct)<1e-10)

y = 4.2462e+03 a = 4.2462e+03

Assertion failed.

4   Fail
R=[2 8 6 7 4 5];k=1;y_correct = 5.33333333333333; a=dont_be_mean(R,k) assert(abs(a-y_correct)<1e-10)

Error using repelem Replication factors must be nonnegative integer-valued scalars or vectors. Error in dont_be_mean (line 5) m = str2num(repelem('1',k-2)); Error in Test4 (line 2) a=dont_be_mean(R,k)

5   Fail
R=0:9; y=0; for k=1:8 y=y+dont_be_mean(R,k); end y_correct=61042519.44444444; assert(abs(y-y_correct)<1e-3)

Error using repelem Replication factors must be nonnegative integer-valued scalars or vectors. Error in dont_be_mean (line 5) m = str2num(repelem('1',k-2)); Error in Test5 (line 4) y=y+dont_be_mean(R,k);
